• “History of civilization is the history of science. The reason lies in the fact that the main difference between today’s civilization and the antiquity is the scientific knowledge. Saints of today are no different than the ancient ones. Today’s artists are no more skillful than the ancient ones.”

• “But the knowledge of our scientists is much more and deeper. So, one of the most cumulative human activity is science. Thus, the most important difference between the two civilizations is in the levels of the scientific knowledge.”

Now you see it, now you don't.
Researchers used the tip of an atomic force microscope to lift a single atom from a surface
(above, before and after) and then replace it (not shown). The method works with nonconducting materials, unlike past atom manipulation techniques.

• Clusters everywhere.
Billions of identical metal clusters can spontaneously form on a silicon surface. Each triangle contains six indium atoms. (With more indium, the clusters fill in some of the empty space, making complete rows and columns of triangles.) The nanoclusters may be useful for electronic devices, for data storage, or for fostering chemical reactions.

By breaking a tiny gold bridge (shown in false color), researchers make electrodes for driving current through a single molecule. Now they have shown a specific way in which the molecule's shape affects its conductivity.

According to experiments, the stretching modifies the quantum states available to electrons, which alters the nanotube's electrical resistance.

İMAM GAZALİ
(1058-1111)
• His book: “ Tehafüt-ül Felasife : Felsefenin
Tutarsızlığı”,Philosophy is not useful,
•
Everything is in Quran.
•
No need to do any research.

İBN-İ RÜŞD (AVERROES)
(1126-1198)
• His book: “Tehafüt-ül Tehafüt:
Tutarsızlığın Tutarsızlığı”. In Spain,
Averroes critisizes Gazali; “Using your mind, you can reach the truth and the religous belief.
”
• West, prospers along İbn-i Rüşd’s philosophy.
• But Madrasah goes along with İmam
Gazali.

• Question comes from the great conqurer.

• Everybody says “Gazali”, including his own teacher
(Hocazade Efendi), except
Alaaddin from Tus, who favors İbn-i Rüşd.
•
Ottoman Madrasah keeps teaching only Gazali.

AND THE RESULT...

• A teacher at madrasah, during the reign of
Beyazıt II, is quoted saying: “Those who do not know geometry, can not judge correctly”
• He is judged, in a tribunal under the presidency of “Sheikh ul-Islam ” and,
• He is hanged Dec. 24,1494 at “At
Meydanı”.

• Sheikh ul-Islam between 1545 –1574,
• He is instrumental in Sultan Süleyman’s receiving the title of Kanuni.
• He is trying to establish the state’s justice systemin a scientific manner.

• In the same period, Mehmed Efendi from
Birgi, is in favor of returning to the basics of islam.
• He divides the sciences into two groups.
• “Useful” which is the teachings of islam.
• “Harmful”all positive sciences and logos(kelam).
• All madrasahs are under Sheikh ul-Islam.

• Müneccimbaşı Takiyyüddin (B: 1526 Egypt) convinces
Murat III, to build an observatory on the hills of Tophane in1577.
• A student of Birgili, Sheikh ul-Islam Kadızade, using the appearence of a comet, and epidemy of plague starting at
1578, convinces the Sultan that this is a result of watching the skys.
• Observatory is demolished on 22 Ocak 1580.
• A real start of going backwards.

• This starts our dark ages that includes: 16th
17th centuries and the first half of 18th century.

• Russian navy destroys Ottoman navy in
Çeşme in 1770.
• The attack is being expected from the Black
Sea, nobody checks the map of Piri Reis.

•
After only the defeats of this order, the reason is found as the lack of knowledge. This brought the need for new establishments.
•
The first educational institute established is
Mühendishane–i Bahri–i Hümayun in1773, which is the base of today’s İstanbul Technical
University.
• The curriculum in this navy school was basically the natural sciences.

• Reform and reorganization (İslahat ve
Tanzimat) starts.
• Darülfünun is established on July 23,
1846.
• But it failed due to lack of interest on the part of students.

• "Darülfünun-u Osmani" is established on
February 20, 1870.
• But this time it was the inedaquacy of the teaching staff and books that caused the closure in 1872.

• Darülfünun-u Sultani is established at
Galatasaray in 1874, with Literature, Law, and Science Departments.
• The lectures were in Turkish and French.
• There is no information about this institution after 1881.

• Darülfunun-u Şahane (İmparatorluk
Üniversitesi) is established September 1
1900 with departments of religion, mathematics and literature.
• Under heavy scuritiny of the the Empire, it was not successful.

• Meşrutiyet (constitutional Monarchy) is declared.
• İstanbul Darülfün un is then established on April
20, 1912, with departments of Law, Medicine,
Literature and Religion.
• But, it had the form of a madrasah, rather than a modern University..

Dünyada herşey için, hayat için başarı için en gerçek yol gösterici bilimdir, fendir. Bilim ve fenin dışında yol gösterici aramak gaflettir,cahilliktir, doğru yoldan sapmaktır.
Bilim ve fen nerede ise oradan alacağız ve her millet ferdinin kafasına koyacağız.

Ben, manevî miras olarak hiçbir ayet, hiçbir dogma, hiçbir donmuş ve kalıplaşmış kural bırakmıyorum. Benim manevî mirasım bilim ve akıldır.
Benden sonra, beni benimsemek isteyenler, bu temel eksen üzerinde akıl ve bilimin rehberliğini kabul ederlerse manevî mirasçılarım olurlar.

Hiçbir zaman hatırlarınızdan
çıkmasın ki,
Cumhuriyet, sizden fikri hür, vicdanı hür, irfanı hür nesiller ister .

1933 University Reform
Atatürk’s notes on Prof. Albert Malche report(29.05.1932)
• Students should know foreign languages,
• President of the University should be concerned with scientific matters. An administrator is needed for administrative business.
• The weakest point in Darülfünun is the education that is not cultivating research skills in students.,
• Library should be improved.

• 1933 Law No. 2252 abolishes
Darülfünun and establishes a new
İstanbul University.
• Istanbul University is thus the first university of the young Republic which opened on August 1, 1933.
• As the Republic celebrates the 10th anniversity, academic year starts in the new university on
November1,1933.

• Prof. Albert Malche was asked to recruit new faculty members from
Europe.

• At September 17, 1933 letter from Einstein to Prime Minister Ismet Inonu pleaded for
Turkey to invite "fourty experienced specialists and prominent scholars... to settle and practice in your country."

He was a professor of Roman and Civil Law at the University of
Leipzig. He then transferred to the University of Zurich and in 1929 moved to the University of Freiburg from which he was dismissed in
1933. He immigrated to Turkey in 1934 and was appointed as professor in the same field at the Law Faculty of the University of
Istanbul where he remained until 1950 when he became guest professor at the University of Freiburg. Schwarz died in Freiburg in
1953. By advising parliamentary commissions and submitting several memoranda for the required changes, he played a significant role in modernizing Turkey’s civil laws during the 1930s,which brought a deep-rooted progress .
He trained an entire generation of Turkish legal scholars.

• came to Turkey in 1933 after being dismissed from the University of Frankfurt am Main and declining an offer from the University of
Amsterdam, which probably saved him from
Nazi persecution when Germany invaded
Holland.

was born in 1900 in Hanover, Germany.Among
the four émigrés he was perhaps the most important contributor to the modernization of Turkey’s public sector. He was dismissed from the University of
Frankfurt on September 1, 1933 and left Frankfurt on
September 22 of the same year. He went to
Switzerland and in the presence of the Turkish
Ambassador Cemal Hüsnü in Geneva signed a renewable five-year contract (October 15, 1933 to
October 15, 1938) to teach social hygiene and statistics.

• Are products of the new Republic, not a continuation of old Darül-fünun.

• events do not happen in an arbitrary manner, but that they reflect a certain underlying order...

• A civilization in
Turkey that does not rely on science cannot compete with the representatives of modern civilization...

• Educating yourself is your own responsibility.
• We should work hard and with love, to educate ourselves in our fields of specialization,
• We should take our education seriously, trying to be world class scholars,
• We should enlighten ourselves, by not graduating solely as technicians.
• We should support our universities.

Everybody should be science-literate....
Scientific thinking...

• Enlightened graduates.

• GOOD LUCK!
